  • A class of exactly solvable models for the Schrodinger equation 

    Downing, C.A. (Springer Verlag, 2013)
    We present a class of confining potentials which allow one to reduce the one-dimensional Schroodinger equation to a named equation of mathematical physics, namely either Bessel's or Whittaker's differential equation. In ...

    Medina, JM; Díaz, JA; Vukusic, P (Optical Society of America, 2015-04-20)

    Hawker, David; Ashwin, Peter (Institute of Physics, 2005)
    We consider a classification of robust heteroclinic cycles in the positive octant of R3 under the action of the symmetry group (Z2)3. We introduce a coding system to represent different classes up to a topological equivalence, ...
  • Classification of wave regimes in excitable systems with linear cross diffusion 

    Tsyganov, M. A.; Biktashev, V. N. (American Physical Society, 2014)
    We consider principal properties of various wave regimes in two selected excitable systems with linear cross diffusion in one spatial dimension observed at different parameter values. This includes fixed-shape propagating ...

    Jones, Andy; Haywood, James M.; Boucher, Olivier (American Geophysical Union (AGU), 2009)
    [1] Theoretical potential geoengineering solutions to the global warming problem have recently been proposed. Here, we present an idealized study of the climate response to deliberately seeding large-scale stratocumulus ...
  • Climate impacts of the southern annular mode simulated by the CMIP3 models 

    Karpechko, Alexey Yu; Gillett, Nathan P.; Marshall, Gareth J.; Screen, James A. (American Meteorological Society, 2009)
    The southern annular mode (SAM) has a well-established impact on climate in the Southern Hemisphere. The strongest response in surface air temperature (SAT) is observed in the Antarctic, but the SAM’s area of influence ...

    Solar geoengineering - deliberate reduction in the amount of solar radiation retained by the Earth - has been proposed as a means of counteracting some of the climatic effects of anthropogenic greenhouse gas emissions. We ...
  • Climate predictions: the influence of nonlinearity and randomness 

    Thompson, J.M.; Sieber, J. (Royal Society, 2012)
    The current threat of global warming and the public demand for confident projections of climate change pose the ultimate challenge to science: predicting the future behaviour of a system of such overwhelming complexity as ...
  • Climate tipping as a noisy bifurcation: a predictive technique 

    Thompson, J.M.; Sieber, J. (Oxford University Press for Institute of Mathematics and its Applications, 2011)
    It is often known, from modelling studies, that a certain mode of climate tipping (of the oceanic thermohaline circulation, for example) is governed by an underlying fold bifurcation. For such a case, we present a scheme ...
  • Climate-Ozone Connections 

    Baldwin, M; Dameris, M (World Meteorological Organization, 2006)
  • Climate–carbon cycle feedback analysis: results from the C4MIP model intercomparison 

    Friedlingstein, P; Cox, Peter M.; Betts, R. A.; Bopp, L.; Von Bloh, W.; Brovkin, Victor; Cadule, P.; Doney, S.; Eby, M.; Fung, I.; Bala, G.; John, J.; Jones, Chris D.; Joos, F.; Kato, T.; Kawamiya, M.; Knorr, W.; Lindsay, K.; Matthews, H.

    Eleven coupled climate-carbon cycle models used a common protocol to study the coupling between climate change and the carbon cycle. The models were forced by historical emissions and the Intergovernmental Panel on Climate ...
  • Climatic impacts of land-use change due to crop yield increases and a universal carbon tax from a scenario model 

    Davies-Barnard, Taraka; Valdes, P.J.; Singarayer, J.S.; Jones, Chris D. (American Meteorological Society, 2014-02)
    Future land cover will have a significant impact on climate and is strongly influenced by the extent of agricultural land use. Differing assumptions of crop yield increase and carbon pricing mitigation strategies affect ...
